Mauri Valtonen,Harry Lehto,Kari Nilsson,Jochen Heidt,L. O. Takalo,A. Sillanpää,Carolin Villforth,M. R. Kidger,G. Poyner,T. Pursimo,Staszek Zola,Staszek Zola,Jin Wu,Xingjiang Zhou,Kozo Sadakane,Marek Drozdz,Dorota Kozieł,Dragomir Marchev,Waldemar Ogloza,C. Porowski,Michal Siwak,G. Stachowski,M. Winiarski,V.-P. Hentunen,M.

TL;DR: The observations confirm the binary nature of the system and also provide evidence for the loss of orbital energy in agreement (within 10 per cent) with the emission of gravitational waves from the system.
Journal ArticleDOI

TL;DR: In this article, the authors analyse optical photopolarimetric monitoring data from 2005 to 2009, during which the latest double-peaked outburst occurred, and propose a new approach to understand OJ 287.

TL;DR: In this article, the authors analyse optical photopolarimetric monitoring data from 2005-2009, during which the latest double-peaked outburst occurred, and assess different binary black hole models proposed to explain the regularly appearing double peaked bursts in OJ287.

TL;DR: In this paper, the authors used a 10 million particle disk to model the accretion disk of the primary black hole and compared the inward flow rate with the historical light curve as well as with the most recent observations reported in this paper.
